It Is Recommend To Intercede With Regard To That Which Is Not Unlawful
Abu Huraira reported it as a marfu' hadith (and the words are):
The deeds are presented on every Thursday and Monday and Allah, the Exalted and Glorious. grants pardon to every person who does not associate anything with Allah except the person in whose (heart) there is rancour against his brother. It would be said: Put both of them off until they are reconciled.
تُعْرَضُ الأَعْمَالُ فِي كُلِّ يَوْمِ خَمِيسٍ وَاثْنَيْنِ فَيَغْفِرُ اللَّهُ عَزَّ وَجَلَّ فِي ذَلِكَ الْيَوْمِ لِكُلِّ امْرِئٍ لاَ يُشْرِكُ بِاللَّهِ شَيْئًا إِلاَّ امْرَأً كَانَتْ بَيْنَهُ وَبَيْنَ أَخِيهِ شَحْنَاءُ فَيُقَالُ ارْكُوا هَذَيْنِ حَتَّى يَصْطَلِحَا ارْكُوا هَذَيْنِ حَتَّى يَصْطَلِحَا
